Bus Cheeks are just what they sound like: cheek ends with bus boards built in on either side. There are enough 16-pin connectors to power thirteen modules, and there are LED indicators for each power rail. Just plug in a power module and you're all set!

Bus Cheeks will work with Synthrotek or Vector brand rails. If you purchase rails from us, you will also get slide nuts and a long 16-pin ribbon cable that runs from one cheek to the other (so that both cheeks light up and distribute power).

These are fully built Bus Cheek ends, but the rails are not stuffed with slide nuts or screwed into the cheeks. This helps to keep the shipping costs down, especially on international orders.

Please note: Bus Cheeks do not have an internal power supply; you will need to connect a power supply to them if you want to distribute power to your modules.

Specifications:

• Supplies power for 13 modules*
• Max module depth: 70mm**
• Power consumption (total for both ends):
• +12V: 0.5mA
• -12V: 0.5mA
• +5V: 6.5mA

*There are 8 connectors on each cheek, but if you plug in a power supply module and run a bus cable between the cheeks, you end up with 13 usable connectors. If you need more connections, you can run one of our Deluxe Flying Bus Cables between the cheeks.

**Modules adjacent to the cheek ends have 15mm of clearance before hitting the red LED and 38mm of clearance before hitting a 16-pin connector. It's a great place for a 2HP passive module or anything shallow.
